To all whom it may concern:

Be it known that I, JOHN E. ANGELL, a citizen of the United States,residing at St. Louis, Missouri, have invented a new and useful Gas orSteam Separator, of which the and containing means to give the gases orsteam, etc. a circuitous course towards the outlet, such last-namedm'eans embodying a semi-cylindrical casing having longitudinal orangular ribs on its outer surface whereby the oil, moisture and otherimpurities will be guided to a receiving chamber to be drawn The objectof my invention is to combine the parts in a novel manner to produce thedesired separation of the oil, impurities, and condensed moisture fromthe passing gases or steam, and to maintain them in such disseminatedrelation so that the deposited and condensed elements may be drawn offwhile the gases and steam pass on to perform their intended functionwithout the undesirable accompaniments.

Various other objects in the combination and arrangement of parts in theresent embodiment of my invention will a so be obvious to those skilledin the art to which this invention pertains without specific mention,reference bein made to' the accompanying drawings, in w ich:

Figure 1 is a longitudinal sectional view of a casing containing myinvention. Fig. 2 is a sectional view of the apparatus takensubstantially along the line 22 of Fig. 4. Fig. 3 is a cross sectionalview on the line 3-3 of Fig. 1. Fig. 4 is a sectional view takenapproximately on the line 4-4 of Fig. 1. Fig. 5 shows the constructionof the apparatus when it is to be connected to a pipe of an angulararrangement. Fig. 6 shows the semitubular extension which rojects intothe casing from the outlet ori ce. Fig. 7 illustrates the constructionand arrangement of parts when combined in a vertical separator. Fig. 8is a cross sectional View taken approximately along the line 88 of Fig.7. Fig. 9

is a sectional view on the line 99 of Fig. 10 and shows a different formof separator including a valve for drawing off the accumulated fluids.Fig. 10 is a cross sectional view taken on the line 1010 of Fig. 9.

y In the embodiment of the invention as illustrated in Figs. 1 to 4,inclusive, the separator comprises a casing formed with a central part11 and two du licate end parts 12 attached thereto, all pro 'erablycylindrical in form. Each end part is formed with an integral annularflange 13. Closure parts 14 and 15 are bolted or otherwise convenientlyattached to the flanges 13 and have tubular projections 16 and 17,respectively, arranged around axial orifices through which the gases orsteam pass. These tubular projections. afford convenient means forconnecting the separator to the pipe or main with which'the apparatus isassociated.- In the arrangement illustrated the gases or steam areadmitted through the orifice in the part 14 and are expelled through theorifice in the part 15.

An inverted U-sha ed flange 18 is rigid with the inner face of t eclosure part 15, and incloses the central orifice between the two armsor sides thereof (Fig. 4). A baflie plate 19 is disposed in proximityto, butsome distance inward from, theinlet orifice. A distrainingpartition, com osed of two plates 20 attached together by bolts throughcontiguous flanges 21, and being inserted U- sha e in cross section, hasone end connected to flhe'flange 18 and the other end bolted to thebaflie plate 19. The baifle plate 19 rests upon the lower side of thecasing and causes the gases or steam to ,pass upward higher than thelower edges of the partition 20 into the large annular chamber betweenthe said partition and the casing. From this annular chamber the steampasses downward under the edges of the partition into a smaller chamberor orifice formed by a semi-tubular auxiliary partition 22 rigid withthe end part 15.

The artition 22 has its edges extending upwar a considerable distanceabove the lower edges of the partition 20, so that the gases or steamwill be deflected downward by the said partition 20 and thence upward bythe sides of the partition 22 into the central chamber between the sidesof said partition 22 and outward through the outlet orifice. Thepartition 22 has a flange 22 on each edge running the entire lengththereof and extended downward to prevent creeping or following by any ofthe undesired substances. It will be obvious that the partition 22 maybe arranged as shown in Fig. 6 with the sides thereof extendingdownward, and, in some instances, when the partition is so used thepartition 20 may be omitted inasmuch as the said partition 22 would thensubserve the functions of both.

A grid or break is interposed between the baffle plate 19 and the inlet,said grid comprising a series of bars 23 rigid with and extendingobliquely downward and outward from'a vertical central bar 24. The endsof said bars 23 are connected and reinforced by rims 25. The bars 23 arepreferably triangular in cross section, and have their apexes towardsthe inlet in order to cause a division of the gases or steam upon thebafiie plate 19 with the least obstruction possible. A rim 26 (Fig. 2)on the bafile plate 19 extends over the upper part of the grid toprevent the substances which become disseminated on the plate frombecoming again entrained by the circulating gases or steam which, asdescribed, pass over said plate. An opening 27 is formed at the bottomor lower edge of the baffle plate to admit the products of separationinto the chamber behind said plate. Upon the surface of the partition 20a series 7 of ribs 28 are formed to assist in the separation of theundesired accompaniments from the gases or steam. These ribs may bearranged, as shown, to extend obliquely downward toward the outlet endof the casing, or they may be arranged parallel with the axis, orvertically, or angularly, or otherwise just as preferred. I haveillustrated only the former method of arrangement for the reason thatsuch other arrangements will be obvious to those skilled in this artwithout specific illustration. The sides of these ribs towards theincoming gases or steam are at an angle to the course of the steam,while the other sides are, or may be, inclined. These ribs form a seriesof channels to conduct the separated accompaniments into troughs 29,formed by the upturned edges of the partition 20. These troughs deflectand prevent the passing gases or steam from again taking up the contentswhich find egress and are dis- 0 iarged therefrom through pipes 30projecting downward a convenient or necessary distance beyond the courseof the gases or steam. The products are, in this manner, gathered inchamber at the bottom of the casing and may be drawn off through a pipe31.

Between the inlet end of the casing and the baffle plate 19 a pipe 23projects a short distance above the inlet orifice and has a multiplicityof perforations 23 in its under side. Through these holes water may besprayed at an angle through the course of the passing gases or steam toremove therefrom such accompaniments as can be .arried by the sprayed.water. The passing gases or steam carry a portion of the sprayed wateragainst the grid or break 23 and also against the baflie plate 19 fromwhich parts the water will wash away the disseminated substances whichgather thereon. By the baffle plate 19 the gases or steam are deflectedupward and some of the water will also be carried upward over and ontothe partition 20. The ribs on the partition, if such are used, willcause additional separation of the water which, by this time, hasabsorbed practically all of the undesired substances accompanying thegases or steam. The latter then pass downward and encounter the troughs29 which. prevent entraimnent of the previously separated substalieeswhich become deposited upon the partition, and which flow into thetroughs. The gases or steam passing under the lower edges of thepartition 20 encounter the auxiliary partition 22 and pass upward overthe edges thereof into the outlet oriliee while the curved edges orflanges 22 cause linal separation of any substances that may then becarried.

In the embodiment of my invention as illustrated in Fig. 5, theapparatus is intended for connection with a pipe or main of angulararrangement. In this form the casing comprises a central part 3;, twoduplicate end parts 33, a closure part 34, and an exit closure part 35attached to flanges on the end parts. The closure part 35 is duplicatein construction and arrangement to the part 15 above described and isprovided with an exit orifice encircled by a tubular projection 36 forconnection with the pipe or main. An internal inverted U-shaped llange37, supports one end of a partitioi'i 38, the opposite end of which isattached to the closure part 34. The partition 38 is constructed similarto the partition 20, having a series of ribs 38) on the side firstencountered by the gases or steam. Through the top of the casing anopening is formed and contains a tubular part 40, attached to the casingby a circumferential llange 41. The tubular part projects into thecasing and, in the embmliment illustrated, supports a. l):1.lll0 plate42, conical in form, and having a peripheral llange or wall 43. A grid,composed of a multiplicity of bars 44, is supported by the wall 43, andsaid bars bend downward at their centers, giving the grid a sunken form.The gases or steam entering through the inlet are injected against thegrid which assists in the separation of the accompanying substances,causing them to deposit on the conical ballle plate 42 whence theyescape through holes 45, and drop to the ribbed partition 33, whosefunction will be readily understood from the previous description of thepartition 20. lln this angular type of separator in which the gases orsteam are injected towards the side of the partition 38, the baffleplate and grid interposed between said partition and the inlet orificemay be omitted, if desired, and the gases or steam made to encounter thepartition first. The ribs on the partition will, in such instances,subserve their usual functions to retain the disseminated substances. Ineither instances the separated substances are directed downward into thetroughs 46 at the lower edges of the partition and thence, through pipes47, to the chamber at the bottom of the casing. A pipe 48 affords egressfrom this chamber. A second partition 49, rigid with the closure part35, and of the same construction, arrangement and function as thepartition 22 previously described, is embraced between the sides of theparti tion 38. The course of the gases and steam and of the products ofseparation will be readily understood by those skilled in this art,without further description, especially as the course of the gases andsteam is clearly indicated by arrows and that of the products by halfarrows.

In Fig. 6 the closure for the exit end of the casing is shown detachedand in inverted form as previously described in connection with thestructure illustrated in Figs. 1 to 4. The same reference characters areused to indicate the various features of the closure as are indicated inFig. 5. It will be readily understood by comparison to Fig. 5 that theclosure may be applied in this inverted form instead of in the mannershown. Preference and any advantages that may be noted in favor ofeither arrangement should determine in specific instances whicharrangement should be used.

In the embodiment of my invention as illustrated in Figs. 7 and 8 theparts eflecting the separation. are inclosed within a cylin-' dricalcasing 50 to one end of which is attached a closure 51 having a centralorifice encircled by an internal tubular projection 52, and encircledexteriorly by an attaching flange 53 whereby the pipe or main 54 may becoupled. To the opposite end of the casing 50 an end part 55 1s securedand-supports a closure part 56 having a central orifice inclosed by anexterior t'ubularprojection 57 provided with an attaching flange 58. Aninterior casing 59 is supported by the end 55 by means of a flange onsaid casing extending into a groove in said end part. The opposite endof the interior casing is closed by a bottom shaped to provide a cone 60which points axlally to the tubular projection 52. The bottom beingcurved to form the cone also forms an annular inverted trough 61. .Thegases or steam which enter through the pipe 52 will be divided by thecone 60 and diverted downward by the trough 61, and the. en trainedfluids will gather therein- An annular trough 62 is supported by thebottom of the interior casing below the trough 61 and forms a sort ofbreak to assist in the dissemination or separation and to receive theseparated substances. A series of pipes 63 extend downward from thetrough 62 to prevent passage of the accumulated substances into thelarge chamber at the lower end of the casing. The gases or steam beingdiverted in the manner just described and as indicated by the arrows inthe drawing, pass into the annular chamber between the interior andouter casings. An opening is formed at one side of the interior casingand is surrounded by an inwardly projecting flange 64. A U-shaped flange66 is on the inner side of the closure 56 and supports one end of apartition 67 the opposite end thereof resting upon the bottom of theinterior casing 59. This partition is constructed just like thepartition 20 having a series of ribs 68 extending in suitablearrangement and direction on its contact surface. The gases or steamentering the interior casing through the opening therein impinge againstthe partition 67 which holds the entrained substances and directs themin the channels formed by the ribs 68 into side trough 69 by whichsaid'substances will be guided downthe chamber' atthe bottom of thecasing may be drawn ofif through an outlet 71. The gases or steam aredirected around the partition 67 and thence around a second partition 72to the outlet and into the pipe or main, circulating the same asdescribed in connection with Fig. 1 to 5 inclusive.

In the form of separator shown in Figs. 9 and 10 a casing 73 of suitableshape is arranged to be connected to the pipe or main, the entering pipebeing indicated by 74 and the outlet pipe by 75. At one side of thecasing an opening is formed of sufficient size to permit insertion of abaffle plate 76. A plate 77 closes the opening in the casing and a screwbolt 78 operates through a hole in said plate and into or against aprojection 79 on the baffle plate and affords means for binding andholding the baffle plate in proper position. The 'bafl'le plate isdisposed at right angles to the inlet pipe and only a short distancetherefrom. A flange on the edge of the plate projects towards the end ofthe casing through which the gases or steam are admitted and preventsaccompanying substances that become disseminated on said plate frombeing drawn in the direction of the passing gases or steam. A break orgrid, comprising a series of angular bars, is ar ranged to receive theimpact of the gases or steam and break them and permit the accompanyingsubstances to gather in disseminated condition on the baffle plate whilethe gases or steam pass over the said plate in circulation as indicatedby the arrows to perform their intended function without the undesiredaccompaniments. The separated substances gather in the bottom of thecasing and pass through a hole 81 in the lower side of the baffle plate.A pipe 82 affords means for drawing off these substances as desired.

Between the baflie plate 76 and the exit end of the casing an invertedU-shaped partition 7 6 is supported and on the upper surface of saidpartition a multiplicity of ribs 76 are formed which may be disposedobliquely, as shown, or axially, or vertically, or angularly, or in anyother desired relation. The circulating gases or steam encounters theseribs and the accompanying substances are thereby distrained. Thispartition is much like the partition 20 in function and arrangement. Thegases or steam are deflected by the partition and the distrainedsubstances are guided downward in the passages formed by the ribs intolongitudinal troughs 7 6 on the lower edges of the partition and thencethrough pipes 7 6 into the chamber at the bottom of the casing. Thegases or steam circulate under these troughs and encounter an auxiliarypartition 7 6 which is semitubular in form like the partition 22previously described, and is embraced between the sides of the partition7 6 somewhat above the lower edges thereof. This partition forms afurther impediment to the undesired accompaniments and causesdistrainment or separation of such substances as may have escapeddissemination by the baffle plate 76 and the partition 7 6. The outletpipe opens into the casing between the two partitions 76 and 76 and thesteam or gases after passing over the edges of said partition 76 passesinto said outlet pipe. In the drawing I have illustrated the twopartitions as an integral casting having a common end part 7'6 throughwhich the outlet pipe 75 opens, but it is obvious that the partitionsmay be detached parts if preferred. The partition 76 has one or morepipes 7 6 forming outlets for any substances that may gather therein. Inconnection with this em bodiment of my invention I provide a valveoperable manually or automatically as desired. At one end of the casing73 a valve support 83 is attached and carries a valve chamber 84. Avalve 85 of known or conventional construction operates in. seats formedin the valve chamber. A post or standard 86 is attached to the valvechamber and the arm of a float 88 is pivoted thereto. A link 89 connectsthe valve 85 and the arm 87 so that when the float is raised above itsidle position it will open the valve and permit the substances in thecasing to flow out therethrough. Manually operable means for opening thevalve comprises a threaded stem 90 operable against the angular end 91effectively to raise the valve. It is obvious that, when suliicientfluid gathers in the casing, the float will be raised and thereby openthe valve to permit flow of the liquid as desired. Obviously this valvedevice may be applied to the other embodiments of my invention as wellas this one.

I have shown and described these embodiments of my invention aspreferred types, but am aware that there may be variations from thecombinations disclosed without variation from the principles of myinvention. I do not, therefore, restrict myself to specific features ormodes of combination, but
